Central artery pulse pressure, not central arterial stiffness impact on all-cause mortality in patients with viral pneumonia infection.

Objectives: COVID-19 viral pneumonia can result in increased arterial stiffness, along with cardiac and systemic inflammatory responses. This study aimed to investigate the association between arterial stiffness, inflammation severity, and all-cause mortality in patients with COVID-19.

Methods: In this study, anthropometric data, pneumonia infection severity, and blood tests were analyzed.

A Novel Index System for Assessing Ventricular-Vascular Coupling.

Background: To explore the value of a novel ventricular-vascular coupling index (VVI) system in relation to age, gender and body mass index (BMI).

Subjects were divided according to age (young [18-44 years], middle-age [45-59 years], old [60-80 years]), gender (male, female), and BMI (overweight/obese [BMI 24], control [BMI 24]).

Relation of myocardial dysfunction to biomarkers, COVID-19 severity and all-cause mortality.

Aims: The COVID-19 infection has been described as affecting myocardial injury. However, the relation between left ventricular global longitudinal strain (GLS), global circumferential strain (GCS) and global radial strain (GRS), disease severity and all-cause mortality in COVID-19 is unclear.

Methods And Results: The study consisted of 220 patients with COVID-19, including 127 (57.

Sequence and directivity in cardiac muscle injury of COVID-19 patients: an observational study.

Objective: To compare cardiac function indicators between mild and moderate to severe COVID-19 patients and to try to identify the sequence and directivity in cardiac muscle injury of COVID-19 patients.

Methods: From December 2022 to January 2023, all patients with laboratory-confirmed SARS-CoV-2 infection in Shanghai General Hospital Jiading Branch were enrolled. The clinical classification was stratified into mild, moderate, or severe groups.

Uncoupling of the center-to-periphery arterial stiffness gradient and pulse pressure amplification in viral pneumonia infection.

Objectives: Arterial stiffness is a common manifestation of viral pneumonia infections, including COVID-19. Nevertheless, the relationship between the center-to-periphery arterial stiffness gradient and pulse pressure amplification (PPA) in infectious diseases remains unclear. This study aimed to investigate this relationship utilizing arterial pressure volume index (API) and arterial velocity pulse index (AVI) ratio.

Relative contributions of arterial stiffness to cardiovascular disease risk score in Chinese women in framingham and China-PAR model.

Background: Arterial stiffness played an important role in the development of cardiovascular disease (CVD) events. The aim of this study was to verify the relative importance of arterial stiffness for different CVD risk scores in a large sample of Chinese women.

Methods: We measured arterial velocity pulse index (AVI) and CVD risk scores in 2220 female participants (mean age 57 years).

Preliminary studies on intimal injury related to stent retrieval in a canine model.

Objective: This pilot study aimed to observe intimal injuries related to stent retrieval in the iliac artery of a canine.

Background: In-stent restenosis remains challenging owing to permanent stent implantation. A retrievable stent may be alternative for intervention without permanent residue.

Arterial Stiffness, Body Mass Index and Cardiovascular Disease Risk in Chinese Females at Various Ages.

Background: This study investigated the correlation in parameters of arterial stiffness and cardiovascular disease (CVD) risk on age and body mass index (BMI) in Chinese females.

Methods: This cross-sectional study enrolled 2220 females. Arterial stiffness was assessed by the measurement of arterial velocity pulse index (AVI) and arterial pressure volume index (API).

Increased arterial pressure volume index and cardiovascular risk score in China.

Background And Objective: The new non-invasive arterial stiffness indices, arterial pressure volume index (API) is explored as a novel marker of residual stress in the wall of the peripheral muscular arteries at zero-stress state in clinical settings. The present study aimed to study the association of API with cardiovascular disease (CVD) risk in China (China-PAR).

Methods: According to China-PAR score, participants were divided into three groups: low risk (< 5%), medium risk (5-9.

Relationship of Arterial Stiffness and Central Hemodynamics With Cardiovascular Risk In Hypertension.

Background: Hypertension is becoming a serious public health problem and noninvasive estimation of central hemodynamics and artery stiffness have been identified as important predictors of cardiovascular disease.

Methods: The study included 4,311 participants, both sex and aged between 20 and 79 years. Arterial velocity pulse index, arterial pressure-volume index (AVI, API, and the index of artery stiffness), central systolic blood pressure, central artery pulse pressure (CSBP, CAPP, and estimated via oscillometric blood pressure monitor), and 10-year risk score of cardiovascular disease in China (China-PAR) and Framingham cardiovascular risk score (FCVRS) were assessed at baseline.

Association of Arterial Stiffness Indices with Framingham Cardiovascular Disease Risk Score.

Purpose: The new non-invasive arterial stiffness indices, arterial velocity pulse index (AVI) and arterial pressure volume index (API) are known to be associated with cardiovascular disease risk. The present study aimed to examine the "dose-response" associations between AVI, API and Framingham cardiovascular disease risk score (FCVRS).

Methods: This survey included individuals with arterial stiffness indices collected at age 18 years and older.

Handheld versus conventional ultrasound for assessing carotid artery in routine volunteers.

Aim: Carotid ultrasound is a key tool for the diagnosis and evaluation of cardio disease, and the measurement of carotid intima-media thickness (CIMT) and hemodynamic parameters is of paramount importance for the imaging method. The aim of this study was to evaluate the feasibility and accuracy of handheld ultrasound devices for measuring carotid parameters.

Methods: We performed a carotid ultrasound on 25 participants using a handheld ultrasound device and a conventional ultrasound machine.

Preoperative diagnosis and prediction of microvascular invasion in hepatocellularcarcinoma by ultrasound elastography.

Background: To assess the values of two elastography techniques combined with serological examination and clinical features in preoperative diagnosis of microvascular invasion in HCC patients.

Methods: A total of 74 patients with single Hepatocellular carcinoma (HCC) were included in this study. Shear wave measurement and real-time tissue elastography were used to evaluate the hardness of tumor-adjacent tissues and tumor tissues, as well as the strain rate ratio per lesion before surgery.
